Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed October 9, 1911. Serial No. 653,751.

To all whom it may concern:

Be it known that I, GrUsnPPn Popvnnmo, a subject of the King of Italy, reslding at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Hinges; and I do declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hinges, and more especially to those having multiple leaves; and the object of the same is to produce an extremely cheap hinge of this character in which the various members are duplicates of each other and may be stamped by a single die and wherein the means by which the members are attached to the articles that they support are automatically held against displacement. These and other objects are accomplished by the construction hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a perspective view of one of my improved hinges made in three members; Fig. 2 is a perspective view of a photograph album whose leaves are shown attached to its covers by means of my improved hinges; Fig. 3 is an upper edge View of one of the group of leaves shown in Fig. 2; Fig. at is an enlarged plan view of the blank from which one of my improved hinge members is made.

As this hinge is intended for use when a number of like members or leaves are to be connected in such manner that they may fold closely upon each other or may be opened outward from and supported by a master leaf or hinge, it will be clear that the hinge members are duplicates of each other with the exception perhaps of that which is outermost on the group of leaves. In the present instance I have shown my improved hinge as applied to a photograph album, whose leaves L are arranged in two groups or banks, each supported by a master leaf M within the box-like receptacle formed by one half of the cover or casing C; but it y will be understood that my improved hinge may have other uses although it is particularly adapted for the purpose to be described and I will explain its details of construction with reference thereto.

As the various members of this improved multiple-leaf hinge are duplicates of each other, a description of one will suffice for all.

Each member is made from a blank 1 stamped in the shape best illustrated in Fig.

t and provided with score lines 2 upon which a it is bent, the projections 3 forming the eyes yet to be described; and the material from which this blank is cut is preferably light sheet metal suitably ornamented and finished so as to be appropriate to the uses to which it is to be put. The blank thus formediis bent into the shape best illustrated in Fig. 1, that portion of the metal between the two lines2 forming a web 4 intended to pass over the upper edge of .the leaf L as seen in Fig. 2, and those portions of the blank on either side of the score lines 2 being bent into parallelism with each other to form the sides 5 and 6. of this member. These sides are pierced with registering perforations 7 through which pass rivets Seas seen in Fig.- 3, their shanks passing through the leaf L between the two sides 5 and 6, and the heads of the rivets in one hinge member abutting against the heads of those inthat next adjacent when the leaves are parallelthereby preventing the dislocation of these fastening; means under ordinary circumstances. The dimensions of the web 4 and the two sides 5 and 6 and their specific shape is not essential, but by preference the inner corners of the sides arerounded oft as seen at 9. The. projections 3 of the blank 1 are here shown as being two'in number on one side and three in number on the other with the spaces between the projections of the last-named side opposite the projections on V the other; and the projections are formed into knuckles 15 and 16 which extend from the inner edges of the side portions 5 and 6 and are deflected a little away from each other as seenin the plan view, Fig. 3. Finally pintles 10 are passed through the registering eyes in the knuckles and headed up at their extremities. The lateral deflection of the knuckles 15 and 16 is obviously for the purpose of causing the axis ofthe pintle to stand on a line midway between the outer faces of the adjacent sides of two hinge members applied to two leaves as will be bestunderstood from Fig. 3, and the fact that the attaching means or rivets 8 have heads projecting a trifle beyond said outer faces causes the necessity for such space. It will be obvious without further illustration that,

in larger hinges it will be quite possible to countersink the heads of the rivets, in which event the lateral deflection of the knuckles will not be so pronounced. Also if the material from which the blank is stamped is somewhat heavier and the thickness of the members L being connected will warrant it, said members may be recessed so that the hinge members will have their sides and webs countersunk into the leaves. However, these details may be left to the manufacturer and user.

In setting up a hinge of this character I will describe it as applied to the leaves of a photograph album. Aseries of said leaves having been connected by a series of the hinge members as illustrated in Fig. 1, a master leaf M is secured within the back or cover C of the album and the knuckles 15 of the sides 5 of one of the endmost hinge members are attached thereto by a pintle like those employed throughout the series. While there may be a greater or lesser number of leaves L than shown, assuming that there are six as illustrated in Fig. 3, the

knuckles 16 of the outermost hinge member of the group will then be removed from the outer side 6, rather than left remaining as shown on the third hinge member at the right of Fig. 1, and the removal of this set of knuckles permits the group to swing neatly into the casing C as shown in Fig. 2. It is to be understood that a set of these hinges is applied to the upper inner corners of the leaves L, and another set reversed is applied to the lower inner corners thereof. When the group of leaves is swung outward it moves bodily around the master leaves M at top and bottom, after which the individual leaves will be separated from each other and moved to and fro around the respective pintles 10 as the photographs are viewed by the user. Afterward they are nested or superimposed upon each other when the heads of the rivet's 8 come into contact, and the group is swung back into the casing C. The cover of the album is here shown as made in two box-like halves connected with each other by hinges H which have no reference to the present invention, but it is obvious that the construction of the album has no bearing on this improved hinge.

What is claimed as new is:

1. The herein described multiple hinge comprising a series of members each consisting' of parallel sides pierced with registering holes, an integral web connecting said sides along their end edges, knuckles projecting from the side edges of said sides and arranged in groups with the knuckles in the group on one side opposite the spaces between the eyes in the group on the other side and the two groups being deflected slightly away from each other, pintles pivotally connecting the eyes of the interengaging knuckles in the contiguous groups of adjacent hinge-members, and rivets passing through said registering holes and the leaves to which the hinges are attached, the heads of the rivets on one member contacting with those of the rivets on the next when the leaves stand parallel.

2. In a multiple hinge, the combination with a series of members each comprising parallel sides with alternately disposed knuckles projecting from their side edges and an integral web connecting their end edges, and pintles connecting the eyes of the interengaging knuckles of contiguous members; of a master hinge-leaf attached to a support at one end of the series and having knuckles interengaging with those on the endmost hinge-member, and a pintle pivotally connecting the eyes of said interengaging knuckles, the knuckles at the outer side of the remote member being removed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
